ProsInexpensive
Having recently purchased an older bike with a 1 inch steerer column this was a great inexpensive way to adapt to the modern 1 1/8 handlebar stem that I already had.

It weighs next to nothing and tightened well inside the aforementioned stem.

I'd recommend this product.

1 1/8 in to 1 in crown race
By

I used to have 1 1/8 hope headset which I was fitted with 1 1/8 in in a '94 Dynatec Diabilo frame. I want to refit the original 1 in threaded forks usin the Hope head set. It seems that I can get a quill to convert at the top, but I can't work out how to fit 1 1/8 Hope Crown race to the old 1 in fork. Will this shim make that possible/practical?
This item is for spacing the stem only and not the headset crown race. SK 16/11/23
Is this alloy?
